Building while life goes on: Christman’s expertise in phased, occupied construction 

When a building can’t stop — neither can we.

Hospitals, universities, government facilities, and historic landmarks rarely have the luxury of closing their doors for construction. Yet those are exactly the environments where The Christman Company excels. We’ve built a reputation for delivering complex, multi-phase projects in occupied buildings where safety, continuity, and precision are essential.

The art and science of phased construction

Working in an occupied building requires more than logistics; it requires empathy, planning and constant communication. Every detail must protect the people inside while allowing construction to move forward.
At Christman, we plan for this balance from day one. Our teams sequence work to maintain operations, isolate active areas, and coordinate with building users to minimize disruption. The result is a process that keeps life moving — safely, quietly, and efficiently — while transformation happens behind the scenes.

Keys to our approach:

  • Phased scheduling that divides work zones strategically.
  • Temporary facilities and utility planning to keep systems operational.
  • Regular communication between project teams, building users, and owners.
  • Rigorous quality control to ensure compliance and performance.

This combination of foresight and flexibility allows Christman to deliver modernization projects without pausing the mission of the buildings we serve.

The Christman Advantage

Through integrated planning, transparent collaboration, and the strength of our experienced self-perform teams, Christman delivers seamless progress in occupied environments—adapting quickly, maintaining safety, and keeping every phase on track.

Case study: Seefeldt building modernization at Northern Virginia Community College

Few projects illustrate this balance better than the Seefeldt Building renovation at Northern Virginia Community College’s Woodbridge Campus.

Originally constructed in the 1970s and expanded in 1990, the Seefeldt Building serves as the academic and administrative core of campus. After decades of use, the college faced mounting maintenance costs and the need for energy-efficient upgrades. Closing the facility wasn’t an option — so Christman developed a multi-phase plan that kept the college fully operational throughout construction.

A temporary 40,000-square-foot modular complex was built first, housing classrooms, labs and offices. This provided uninterrupted academic continuity while the main building underwent a full modernization, including façade replacement, new MEP systems, accessibility upgrades, and state-of-the-art teaching environments.
